Abstract

The invention provides a dual-side type liquid crystal display device which includes a front light subassembly, a liquid crystal panel group, a first polarized light membrane and a switch type liquid crystal thin film. The front light subassembly includes a front light unit and a light source group; the liquid crystal panel group is set on an anti-reflection face side of the front light unit which includes a liquid crystal panel and a light filter plate; the first polarized light membrane is set between the liquid crystal panel group and the front light subassembly; the switch type liquid crystal thin film is set on a second surface side of the liquid crystal panel, or the reflection transmission plane side, and the switch type thin film can be switched between a first transparent state and a second nontransparent state.

Description

[0001] This application is a divisional application of an invention patent application filed by AU Optronics Co., Ltd. on January 6, 2005, entitled "Portable Electronic Device and Its Double-sided Liquid Crystal Display Device" and application number 200510004111.0 technical field [0002] The present invention relates to a portable electronic device and its double-sided liquid crystal display device, and in particular to a portable electronic device with a double-sided liquid crystal display device arranged on a cover. Background technique [0003] With the advancement of display technology, display devices have continuously evolved from traditional cathode ray tubes (CRTs) to produce various new display devices. Among them, liquid crystal display (LCD) has the advantages of thinness, power saving, low radiation, etc., so it has gradually become one of the common display devices today, and can be widely used in notebook computers, digital cameras, camcorders, mobile phones a...
